X-RAY CABINET.

Specification of Letters Patent. Patented Jun@ 13, 31922.

Application filed January 24, 1919. Serial No. 272,823.

'To all whom it may concern Be it known that I, EDWIN L. EDWARDS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful X-Ray Cabinet, of which the following is a specification.

It is the object of my invention to provide a self-contained X-ray cabinet, which can be used both as a protective enclosure for the operator and as a dark room for developing the negatives, and which swingingly supports the X-ray tube and a seat for the patient so that said tube and seat may be swung either into operative position outside the cabinet or into,inoperative position Within the cabinet.

The accompanying drawing illustrates my invention: Fig. 1 is a perspective View of an X-i'ay cabinet embodying my invention, with the parts in operative position; Fig. 2 1 s a somewhat similar perspective View, showing the interior of the cabinet, and with the tubecariying door partly broken away; Fig. 3 is a horizontal section through the cabinet, with the lworking parts within it.

The cabinet has a top 10, a bottom 11, and three fixed sides 12, 13, and 14., conveniently supported on suitable feet lpthese three sides and the top and bottom and feet being relatively iixed and constituting a supporting stand. Conveniently the cabinet is of suitable height to receive a man standing up. At the free front edges of the sides 12 and 14 are hinged two doors 16 and 17. These two doors overlap with the door 17 outermost, as indicated in Fig. 3, so that the cabinet may be closed by such outer door 17 whether the inner door 16 is closed or open. In the latter case, at least, the closing of the cabinet by the Outer door 17 is preferably light-tight. The inner door 16 may be swung either to the closed inoperative position shown in Fig. 3 or to the open, operative position shown in Fig. 1, in which latter position it lies against the outer face of the side wall 12; the hinges 18 on which said inner door 16 is mounted permit swinging of the door through 270 to accomplish this.

On what is its inner surface when it is closed the inner door 16 carries near the bottom a patients seat 19, which is preferably a suitable form of folding seat as illustrated, and near the top an adjustable support 20 for an X-ray tube 21; so that the seat and tube are on what is the outer surface of the d oor 16 when such door is fully open and lies against the wall 12, but are folded into the space within the cabinet when such door is closed, The same face of the door 16 may be provided with an adjustable headrest 22, for the patients head. B Y manipulating the support 20 in the usual lway, the rays from the tube 21 may be directed as desired. The terminals of the tube 21 are connected by suitable conductors 23 to the outer ends of insulating posts 24 fixed to the same face of thedoor 16; and these posts 24 are provided with spring fingers 25 connected to `the conductors 23 and arranged to engage corresponding spring lingers 26 on forwardly proJecting insulating posts 27 carried by the cabinet top 10. The spring fingers 26 are connected by suitable conductors 28 to the secondary terminals 29 of a suitable high-tension transformer 30, mounted on the cabinet 10. Thus the connections from the X-ray tube 21 to the transformer 30 are made and broken by the swinging of the inner door 16.

At about the height of a mans eyes, the wall 12 is provided with a window opening 31, which may receive any desired glass 32, 'such as lead glass when the X-ray apparatus is in use, a ruby glass when the cabinet is used for developing purposes, and an opalite glass to examine negatives. If desired, the ruby glass may be removably superposed over the lead glass, so that it may be put into or out of position at will; or the window may be provided with glass-receiving slideways 33 in which either a ruby glass or a lead glass may be placed as desired. The door 16 is provided with an opening 34 which registers with the window 31 when such door is swung back against the wall 12. In order to protect the operator, a screen formed by a layer of lead 35 or other material opaque to X-rays is mounted between the tube and the operator, as in the side Wall 12 as shown in Fig. 3, and if desired in any of the other side walls or in the doors 16 and 17, though ordinarily such a protective layer in the side wall 12 is suficient.

Mounted within the cabinet are the electrical controlling devices, such as a switch 36 and a rheostat 37 and also mounted within the cabinet is a developing tank 38. The

developing tank is preferably on the wall 12 below the window 31, and the electrical controlling devices are preferably on the wall 13, as is clear from Figs. 2 and 3.

When the cabinet is not in use, the doors 16 and 17 are both closed, and the X-ray tube 21 and its support and the patients seat 19 are folded within the cabinet. Vhen the cabinet is in use, the inner door 16 is swung open so that it lies against the side wall 12, thus connecting the X-ray tube 2l to the transformer 30 by the interengagement of the spring fingers 25 and 26. The patient is placed in proper position on the seat 19, the support 2O is adjusted so that the rays from the tube 21 will be directed in the desired direction, and the plate or lrn to be exposed is put in position. Then the operator enters the cabinet, preferably closing the door 17 behind him, and manipulates the controlling devices, such as the switch 36 and rheostat 37, to produce the desired eX- posure. Then the operator comes out and gets the exposed film or plate; and if he wishes may immediately return into the cabinet and develop such film or plate in the developing tank 38, the door 17 being closed and the ruby glass being in position over the window 31 during such developing.
